    Abstract: A torque transmitting mechanism includes a drum attached to one of a first member and a second member, and a shell attached to another of the first member and the second member. The drum and the shell are concentrically disposed about a longitudinal axis, with the shell concentrically disposed about the drum. An electric motor includes a stator, and a first rotor rotatable about the longitudinal axis relative to the stator. A band is coupled to the shell, wrapped around the drum between four and twelve complete revolutions, and includes a first end attached to the first rotor for rotation with the first rotor. The band includes a second end attached to a reaction member. Rotation of the first rotor tightens the band against the drum to bias the drum against the shell, to transmit torque between the first member and the second member.

    Abstract: A vehicle includes a passenger compartment having a first row of seats and a second row of seats disposed behind the first row of seats. The second row of seats including a seat back configured to fold forward toward the first row of seats. The seat back of the second row of seats further including at least one headrest that is movable from a retracted position to an extended position. The at least one headrest includes a retraction mechanism configured to retract the headrest to a retracted position automatically when the seat back of the second row of seats is folded forward.

    Abstract: An aqueous precursor liquid for forming an anti-fouling heterophasic thermoset polymeric coating is provided. The precursor liquid includes a first fluorine-containing polyol precursor having a functionality >about 2 that forms a fluorine-containing polymer component defining a first phase in the coating. The precursor liquid also includes a second precursor that forms a second component present as a second phase. The first phase can be a continuous phase and the second phase can be a discrete phase, or the second phase can be the continuous phase and the first phase can be the discrete phase. The discrete phase includes a plurality of domains each having an average size of ≥to about 500 nm to ≤to about 25,000 nm. A crosslinking agent, water, and optional acid or base are also present. Methods of making anti-fouling heterophasic thermoset polymeric coatings with such precursors are also provided.

    Abstract: The knitted textiles include a knitted structure including a plurality of hollow yarns. Each hollow yarn includes a yarn body and defines a yarn hole extending through the yarn body to allow expansion of the yarn body upon inflation of each hollow yarn through the yarn hole. The knitted structure is configured to transition from an unexpanded state to an expanded state in response to the inflation of the hollow yarns through the yarn hole. The knitted structure has a first porosity in the unexpanded state, and the knitted structure has a second porosity in the expanded state. The second porosity is less than the first porosity such that a visibility through the knitted structure is greater when the knitted structure is in the unexpanded state than when the knitted structure is in the expanded state.

    Abstract: A shield assembly is employed for a friction brake used to decelerate a road wheel of a vehicle. The vehicle has a body with a first body end configured to face an incident ambient airflow, a second body end opposite of the first body end, and an underbody section spanning a distance between the first and second ends. The shield assembly includes a first shield component arranged proximate the brake and rotationally fixed relative to the vehicle body. The shield assembly also includes a second shield component operatively connected to the first shield component for shifting relative thereto. The shield assembly additionally includes an actuator employing a shape memory alloy element to shift the second shield component relative to the first shield component in response to a temperature of the brake to thereby direct at least a portion of the airflow to the brake and control temperature thereof.
